If it is leaking into the connector I do not think the oring will fix it. If it is leaking just between the sensor and the mating surface it would. So just depends on the leak. Once oil is getting into the connector, the part is just done and should be replaced for sure. Oil in that connector will cause it to degrade and fail over time. I cleaned the harness connector as well as I could with some contact cleaner and some degreaser and replaced the switch. I think the honda part can be had for $50ish and aftermarket ones were around $30.
Also, oil sometime accumulates on a frame part. Kinda hidden from the ground. Then continues to drip a few drops, for a week or two.
Yep, after an oil change, look for and wipe any off that may have spilled from the filter. Saves some anxiety later After I cussed and tore up my arms dealing with some of the coolant lines. I noticed coolant dripping on the ground after bleeding it RIGHT under the area I had worked on. I was about to get upset, but looked and did not see the leak, cleaned it up, and then poured water where the bleeder valve is. Guess where it dripped out? All was good, but almost tricked myself in to being upset there!

Did you pre-fill the oil filter before fitting it on?
If so, sometimes, oil gets spilled in the inner "lip" of the filter where you can't wipe it up, and dribbles out later.
This will be evidenced by the bottom of the filter being slightly oily, or a visible droplet on the bottom edge of the filter.
I would wipe it up with a rag soaked in dawn/water and re-monitor. Don't spray brake cleaner to clean the oil off the hoses. You will deteriorate the hoses and any rubber gaskets that it gets on
Do clean the hoses with warm soapy water though. And when changing oil look for any that dripped onto it and wipe it off quickly to avoid long term exposure. The oil exposure will cause them to fail over time. It penetrates the rubber and causes it to slowly soften and swell and eventually fail. Just do not use anything else that is damaging to rubber to clean them obviously. Any oil exposure to them is not good, but at least getting it cleaned off right away should limit or slow down any damage. Monitor that hose now when you change the oil each time and if it starts to look swollen it should be replaced. It is a molded hose due to the sharp bend and thus, a quick fix with regular heater hose does not work without kinking the hose, so if it fails you are down until a replacement arrives. Since you are dealing with the issue right away here and will clean it all up, it may be ok this time around but I would still keep an eye on it.
Checked the pressure switch. While it looks clean, there was oil on the pigtail, and the connection. I’ll see if I can order a new switch and get it changed out this week.
thanks guys! Looks clean and oil free at first but a closer inspection revealed oil leakage.
Many parts for our cars are unique, many shared. This one seems like obvious candidate to be shared. So no surprise it might also fit Prelude.
But then that also makes paet more appealing target for forgery. Replica part, replixa packaging. That is rampant on Amazon. I'd prefer an aftermarket part over a replica. At least aftermarket trying to create a positive rep.
